Wireless printing setup error

[MEickhoff]

I am able to print via a USB cord from my Mac, but no longer able to print wirelessly. The printer did print wirelessly at one time, but the printer would always go into standby and the computer couldn't wake it up. I noticed there was an update to fix this problem, but now I can't get the printer to find my wireless network. In the setup assistant in Network Setup I get an error message saying the Wi-Fi network is not within reach of the device but everything is here in the same room and I am sure the Wi-Fi is working! Help!

To Meickhoff: Based on your mentions of having to patch the firmware I assume its the Photosmart C4580 that you have. When running the setup for this unit there are 2 main causes for it to say the network is not in reach when it should be.

The first is that the router may be using an incompatible frequency. All routers should broadcast in 802.11 (with a further letter coding). The printer will only locate the wireless 802.11G signals. Many new routers though broadcast in 802.11N by default. If yours is an N router then you should be able to change that back to G from your routers control panel.

The other cause is based on your SSID (The name for your wireless signal). If you have any symbols in it, the printer is likely removing them when it searchs for the signal. If this is the case, try adjusting the signal name to remove any symbol characters.

802.11n routers, by default, are compatible with our 802.11g printers -- they interoperate just fine.  The only way to wreck the compatibility is if you run the wireless-router in 802.11n-only mode.

Let's get some data first on your environment:

• what kind of printer do you have?
• what kind of wireless-router do you have?
• what Mac OS are you running?
• between the time the printer was working wirelessly and now that it's not working wirelessly, do you make any changes to your wireless network?
• is the radio on the printer on (look for the blue wireless LED)?

Finally, try following the instructions from this video to manually get the printer on your network.  Once the printer is on the network, verify that you can access the printer by looking for it in the Bonjour bookmarks from your Safari browser (Bookmarks -> Show All Bookmarks - > Bonjour).  Then follow up by reinstalling the SW (unless you have Snow Leopard -- in which case the drivers are built in to the OS).
